The NFL has expanded its Thursday Night Football TV deal, and it could lead to more significant opportunities down the road. The NFL and CBS had partnered to split the TNF schedule, and in 2016, that will be split a third way. NBC is joining the mix. NBC and CBS will each broadcast five games, and NFL Network will broadcast the remaining games, plus Saturday Night Football and other assorted games. I don't believe this covers the Thursday opener in Week 1.
The NFL is also negotiating a live stream option, and I imagine that will be announced sometime soon.
